How do you change the blower motor resistor on a 2001 Dodge Dakota?
Under the passenger side dash/glovebox you will see a wiring
harness/connector. It can be hard to see unless you lay on your
back on the passenger floor. you will need a socket-and a
flashlight/light of some kind. An extension for your socket wrench
MAY help you get the right bolt out. If you are having trouble
getting the left bolt out you may need to remove the front bolt
from the plenum (the thing the air comes from when set to
floor/feet). There is a pain in the butt bolt behind the plenum
that you may need to loosen to get enough room to move the plenum
out of the way. Carefully push the plenum to the front of the truck
being careful to not break it! You just need enough room to get the
resistor bolt out.
Once you fight with the wiring harness and get it disconnected
READ THE RESISTOR INSTRUCTIONS! The new ones have extra tabs that
MUST be cut off, if this is the case there will be an instruction
sheet with the new resistor. I used a good pair of kitchen
Before installing the new one inspect the old one. If there is a
burnt looking pin (usually #2-second pin from left-there should be
numbers on both resistors) you will need to get a new wiring
harness, unfortunately I can only find one at the dealer or a
If everything looks good or you have now replaced the harness
bolt in the new resistor then carefully pull the plenum back into
place. It needs to fit correctly to work. There is a bit of flimsy
foam that needs to be in the right place so it won't block airflow.
If you accidentally ripped this off you can do 1 of 2 things.
1) use camper tape on the piece the plenum goes over. in other
words the piece that is attached to the truck not the removable
plenum. It will have to be thin camper tape
2) duct tape the outside of the plenum. there are other tapes
you can use but you need to be able to remove the tape for future
